' b r /7Z whom it may concern:

Be it known that I, PETER E. ERICKSON, a citizen of the United States, and a resident of Port Chester, in the county of lVestches' 'ter and State of Xew York, have invented la new and Improved Lubricator for Leaf- Springs, of which'the following is a full,

lean and exact description. v

The object of the invention is to provide a new and improved lubricating device for lubricating leaf springs of automobiles and other vehicles to prevent such springs from squeaking and to Ireduee the wear thereof. to aminimum. In order to accomplish the desired result, use is made of means for prying adjacent leaves apart and passing a lubricant between the pried open leaves.

Figure 1 is a side elevation of the .lubri-,

eating device as applied, parts being shown in section; Fig. 2 is a transverse section of the same on the line 2-2 of Fig. 1; and Fig. 3 is a similar view of the same on the line 33 of Fig. 1.

The lubricating deviceis mounted on a support A, preferably in the form of a rod or bar, on one end of which is adjustably secured a spreading member B by the use of a set screw C. The spreading member I3 is provided on its inner face with a trans versely-extending V-shaped lip .D adapted to pass between adjacent leaves of a leaf spring E at one side thereof, as plainly indi-, cated in Fig. 1. On the supporting bar A is mounted to slide a prying member F provided with a tubular or hollow prying point 1r having a transversely-extending V -shaped lip G located directly opposite the prying lip D to pass between the adjacent leaves of the leaf spring E at the opposite sides thereof, as will be readily understood hv reference to Fig. 1. The opening G in the oint G is incommunication with an aperture F formed in the member F and in communication with the interior of a container H for containing the lubricant.

In order to move the prying member F. and its point G toward the other prying member I3, use is made of a screw rod I- screwing in a nut J secured to the supporting bar A ad acent the prying member F.

the said screw rod I abutting against theback of the prying member F so that when the handle I of the screw rod I is turned, the said prying member I is moved toward the prving member It to cause the lips I) and G to pass between adjacent leaves with a view to pry the same open. In order to hold the support A, use is made of a guide rod J extending from the bottom of the nut J and engaging a guideway F 2 formed on the bottom of the movable prying member F. A spring K is coiled on the support Aand presses with one end on the prying member 13 and presses with its other member F so that when the screw rod I is retracted, the spring moves the prying member. F outward to disengage the lips D and ir' from the previously pried openleaves of the spring I. The point Gis preferably screwed in the prying member. F andsecured therein by a-set screw L to permit of conveniently removing the said point G for replacement by a new one in case it is worn on In using theflubricating device the screw rod I is retracted so that the lips D and G are a distance apart somewhat in excess of the width of the spring E to allow of plac ing the edges of the lips D and'G at the joint between the adjacent leaves of the end the prying.

this position is reached the operator screws .up the cover of the container H to force some of the lubricant out of the container and by way of the apertures F and G between the pried open leaves of the spring E.

The operator next retracts the screw rod I so that the member F is returned to its former position by the action of the spring K. whereby the lips D and (.lr are disengaged from between the leaves of the spring E to allow the said leav'es to returnloy their own resiliency with the lubricant interposed between the said leaves, thus lubricating the same.

very simple topl is provided for conveniently spreading the members apart'and passing a lubricant between the pried open leaves.

Having" thus described my invention, I (ilaim as new gyu'li desire to sceureby Letters atent:

l. A.|eaf spring\sepai'ator and lubricator,

comprising a support, a prying men'iber adjustably mounted on one end of the support, a out on the other end of the support, a sec- .mnd prying member mounted to slide but not From the foregoing it will be seen that a to turn on the support, a spring on the support between the prying members, a lubricant container carried by the sliding prying member, and a screw mounted in the nut and engaging the sliding prying member.

2. A leaf spring separator and lubricator, comprising a rod, a prying member on one end of the rod and having a V-shaped lip, a nut on the other end of the rod and having a guide arm projecting therefrom, a second prying member mounted to slide onthe rod and having a hollow V-shaped lip, said prying member having a passage with which the hollow lip communicates and provided with a guide way receiving the guide arm of the nut, a lubricant container carried by the slidable prying member, and a screw mounted in the nut and engaging the said slidable prying member.

3. A leaf spring separator and lubricator,

comprising a rod, a prying member adjustably secured to one end of the rod and having a V-shaped lip,' a nut secured to the other end of the rod and having a guide arm extending therefrom, a second prying member slidably mounted on the rod and having a hollow V-shaped lip detachably secured thereto, said prying member having a pasage with which the hollow lip communicates and provided with a gmdeWa-y receiv ing the guide arm or" the nut, a spring on the rod between the prying members, a lubricant container carried by the slidable prying member, and a screw mounted in the said nut and engaging the slidable prying member. I

4. A lubricating device for lubricating leaf springs, comprising a support, prying members for prying adjacent leaves of the spr h open, one of the said pryingmembers being secured to the said support and the other being movable thereon the said movable prying member being hollow, a lubricant container attached to the said movable hollow prying member and in communication therewith to pass a lubricant between the said open leaves, manually-controlled actiiating means for moving the said movable prying;

member toward the said fixed prying member, and a spring'on the said support and pressing the said movable hollow prying member to return the latter on retracting" the said actuating means.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
